roles/common: rework fail2ban again
Actually, we do want to run fail2ban on all hosts because the sshd
monitoring via systemd is nice. At the very least it reduces spam
from failed logins in our systemd journal.

roles/common: rework fail2ban tasks
We can only run fail2ban when we have logs to monitor. When a host
is running Caddy we don't have logs, so fail2ban doesn't have any-
thing to monitor out of the box. For now I will restrict the task
to hosts running nginx.

While testing Debian 12 on Scaleway I noticed their apt sources.list

those hosts.

roles/common: create /etc/apt/keyrings
According the the Debian docs for third-party repositories we must
create this manually on distros before Debian 12 and Ubuntu 22.04.
This is due to changes in apt-secure and the deprecation of apt-key.

roles: don't compare literal true and false
I changed these yesterday when editing the truthy values, but acco-

without comparing.

roles: strict truthy values
According to Ansible we can use yes, true, True, "or any quoted st-
ring" for a boolean true, but ansible-lint wants us to use either
true or false.

roles/common: Update list of abusive IP addresses
This comes from the AbuseIPDB with a confidence level of 95%. I use
the following command to download and sort the IPs:

  $ curl -G https://api.abuseipdb.com/api/v2/blacklist -d \
    confidenceMinimum=95 -H "Key: $ABUSEIPDB_API_KEY" \
    -H "Accept: text/plain" | sort | sed -e '/:/w /tmp/ipv6.txt' \
    -e '/:/d' > /tmp/ipv4.txt

I manually add the XML formatting to each file and run them through
tidy:

  $ tidy -xml -utf8 -m -iq -w 0 roles/common/files/abusers-ipv4.xml
  $ tidy -xml -utf8 -m -iq -w 0 roles/common/files/abusers-ipv6.xml

Then I formatted the nftables files manually. Meh...

roles/common: use pyinotify backend for nginx fail2ban jail
This seems to be automatically selected, but on some other servers
I notice it is not. I will set it here explicitly so fail2ban does
not fall back to the inefficient "polling" or incorrect "systemd"
backends.

roles/common: Disable unsafe Diffie-Hellman SSH moduli
The WeakDH team showed (in 2015) that Diffie-Hellman key exchange
with prime number groups of 1024 bits or less were weaker than we
previously thought, and well within the reach of nation states. They
recommended (in 2015) using 2048-bit or higher prime groups.

The SSH audit project recommends that we should use 3072-bit now.
